TYBEfWM'E'ING' MACHINE.

To au whom t may concern Bre it known thatl', 'JOHN C. MCLAUGH- L1 Nacitizen of the United States, residing in the county of Hudson land Stateof New Jersey, have invented certain new and useful Improvements in TypelWriting Machines, of which the following is a specification.

This invention relates to paper cQntrol-i ling means for typewriting machines.

My improvement relates to means for adjusting the paper shelf so that itwill fit. closely around the bottom of the platen i' desired in using thin sheets, but it can be adjusted to take lhir-k laycrs'of paper, or to permit sheets to b e introduced at the front of the platen. f

The invention l have: illustrated as applied to an Underwood machine. The paper shelf is shown arranged to slide up and down on .the usual rod which reinforces or supports it, and it is easily adjusted thereon by means of a handle.

In the accompanying drawings, Figure 1 represents a perspective view of my improvement as applied to the pla-teirframe or carriage of an Underwood typewriter. Fig. 2 is a transverse section of the same. Figs. 3 and 4 are rear views showing the parts in various positions. Fig. 5 is a section of Fig. 2 on the line 5-5.

In the drawings in the usual way on the end plates 2 of a platen-.frame 3 on which it may be turned by knob f1. At t-heback of the end-plates 2 of the plateufra-me, extending across an connecting them. is a bar 5 on which the usual paper shelf 6 is supported. The shelf is shown extending forwardly and curving under the platen and' around to the front at 6a.

The means of support 4herein ishown, comprises two vstuds 'or pins Tf fixed on the paper-shelf and extending through openings or slots 8 of said bar 5. These pins are ivoted to levers 9 and 10,-pivoted at 11 an 12 in said bar 5 respectively; Said levers 9 and 10 are loosely linked together by a pin 13, and lever 9 is extended at one end to .form a handle 14, by which it may be moved.

Thus it will be seen that the two levers move together, swinging Iaround their pivots, and are adapted to move the shelf 6 nearer and farther from the bottom of the platen 1 by Specification et Letters Patent. Application @led September 28, w11.

i The platen t v Fig. 3,

" 'Having thus described my 1 is the platen supported .around said platen, a

Patented Ang. 1&1913. serial no. 651,723.'

vmoving the pins 7 the curved guide or apron 6a always keeping in parallelism with the platen.

0n lever 9 is provided a spring 15 havin@ a detent 16, which is adapted to tit in one of aseriesof holes 17 on a guide 18, under` which lever 9 passes, and thus lock the paper shelf inany desired position, to accommodate varying thicknesses of the work.

frame is provided with the usual r'od 19, carrying the front pressure rolls Q() for holding the paper in place. in 'the paper shelf 6 is shown raised, to guide thin sheets` and in Fig. f1 depressed, to accommodate thick sheets, or to permit sheets'to be inserted downwardly at lthe front of the platen and rearwardly under the same.

ln operation, the guide 6a is first depressed, the paper is inserted attlie back from above in the usual manner (or a the front), then` the guide 6 is readjnsted to suit the work in hand, and the platen is turned. The paper may be passed under the adjustable pressure rolls 2.0 andthen alined.-

Variations .may be resorted to within the scope of the invention, and portions of the improvementsy may be used without others. invention, l

claim: w

1. In a typewriter, the combination of a platen, a .platen frame, rolls adapted to press a sheet against said platen, a paper shelf cooperating with said rolls to hold a sheet.

against said platen', a bar supported from' the sides of said platen frame, members supported on said bar carrying said paper shelf, and means connecting said carrying means to set said paper shelf bodily up and down to and from said platen.

2. 'In a typewriter nat-ion with a platen, encircling said platen of a member partially for guiding a sheet bar on said carriagi'f. slots in said bar, )ins riding in said slots and supporting sai encirclingr niember, and means formoving said pins in said slots.

Inatypewriting machine, the combination with a platen frame and a platen journaled therein, of a paper shelf at the rea r ot the platen and curving forwardly beneath and around the Same to form a paper-guiding apron, Ameans connecting said paper `carriage, the combi shelf and apron to said platen 'frame for adjusting the apron bodily downward, to clear a passage forl the introduction of the Work, and means for locking the paper shelf and apron in dilierent Working posit-ions.`

4. The combination With a platen andl platen frame in Wliieli it is journaled, of a combined paper shelf and gu1d1ngapron curving around tlie platen, means for lowering said paper shelf and apron'bodily to faa'platen and a platen frame, of a member partially encircling said platen for guiding a sheet around said platen, said platen frame having a bar, slots in said bar, pins riding in said slots, levers pivoted on the bar connecting said pins, a handle for moving said levers, and locking means for said handle.l

6. The combination of a platen, a platen frame, a shelf curving around the under side of the platen to guide the sheets around the same, and means to guide the shelf'- bodily upl and down, including a linkage connectvin'of saidshelf to said platen frame for 1 frame, a'slielf curving around the under side of the platen to guide the sheets around the same, and means .to move the shelf bodily up and down, including a linkage connecting said shelf to said platen frame for bodily movement in parallel lines; said linkage comprising two levers pivotally connected t0 each other and each pivoted to the platen frame. l

8. Thev combination of a platen, a platen frame, ashelf curving around the under side of the platen to' guide the sheets around the same, means to guide the sheli= bodily up and down, including a linkage connect-ing saidl shelf to saidv platen frame for bodily movement in parallel lines, and means for locking said apron in different Working po- A.si tions.
